Hillside Center I and II on Hillside Court, leased to government contractor BAE Systems and other tenants, was sold by Corinthian Realty Partners. The two-building complex has a total of 86,000 square feet.

The sale is the second in Columbia in the last two weeks for Cassidy Turley, which also helped arrange the $13.6 million sale of Stevens Forest Green, an 82,400-square-foot office building that New Boston Fund bought earlier this month.
